Drop special handling of host component with slashes to mean
Unix-domain socket. Specify it as separate parameter or using
percent-encoding now.
Allow omitting username, password, and port even if the corresponding
designators are present in URI.
Handle percent-encoding in query parameter keywords.

some documentation improvements by myself
postgres:// URIs are an attempt to "stop the bleeding" in this general
area that has been said to occur due to external projects adopting their
own syntaxes. The syntaxes supported by this patch:
postgres://[user[:pwd]@][unix-socket][:port[/dbname]][?param1=value1&...]
postgres://[user[:pwd]@][net-location][:port][/dbname][?param1=value1&...]
should be enough to cover most interesting cases without having to
resort to "param=value" pairs, but those are provided for the cases that
need them regardless.
libpq documentation has been shuffled around a bit, to avoid stuffing
all the format details into the PQconnectdbParams description, which was
already a bit overwhelming. The list of keywords has moved to its own
subsection, and the details on the URI format live in another subsection.
This includes a simple test program, as requested in discussion, to
ensure that interesting corner cases continue to work appropriately in
the future.

Oh, it also supports postgresql:// but that's probably just an accident.
